A low-temperature atmospheric plasma generating device

technical field

The utility model relates to a low-temperature atmospheric plasma generating device, which is easy to disassemble and assemble, has a simple structure and only has a single air chamber, and can generate plasma with stable performance, high reliability and excellent effect with low power.

Background technique

Plasma is a form of matter mainly composed of free electrons and charged ions. It exists widely in the universe and is often regarded as the fourth form of matter besides solid, liquid, and gas. Called the plasma state, or plasma state.

On the surface of the earth, although there are natural plasma states, such as lightning, aurora, etc., there are not many. Most of the plasmas we come into contact with are man-made plasmas, such as common fluorescent lights, neon lights, rocket exhaust, and now the most popular plasma TV. With the development of science and technology and the progress of society, human beings have become more and more dependent on plasma, and artificial plasma has been widely used in laboratories and industries, showing a broader prospect.

At present, the best way to dissociate neutral gas atoms is to apply an electric field, so that the electrons in the electric field will be attracted by the positively charged electric field and accelerate. During the acceleration process, the electrons can accumulate energy. When the electrons When the energy reaches a certain level, it has the ability to dissociate neutral gas atoms to achieve the desired plasma state.

However, existing plasma-making components often have different electrode service life due to differences in electrode material, gasification characteristics, electrical conductivity, and melting point.

As shown in Figure 1, the most common plasma structure 100 has the following disadvantages:

1. The structure is complex, and there are front and rear double air chambers inside. Although the pressurization force is relatively large, the noise generated is often beyond the range that the human ear can bear.

2. Because there are conductive materials such as graphite in the center of the interior, the design of the double air chamber is likely to cause a discharge effect in the front air chamber, so that the conductive materials are burned.

3. There is a barrier layer in the nozzle structure, but the overall planning and design are improper, and the inner seal is not easy to replace. Once the conductive material is burned, it needs to be replaced, but its accuracy is not easy to control.
